Most of the speculation surrounding the iPhone 5, assuming that's what Apple is going to call its next-gen iPhone, has centered on how big the display will be and otherwise more marketable features such as 4G LTE support.
But over the past few days, more information has emerged regarding what we can expect to find on the inside of the iPhone 5. 9to5Mac reported yesterday that the the iPhone will see the inclusion of a few new snazzy chips.
For instance, the iPhone 5 will purportedly house a Broadcom BCM4334, a wireless chip sporting an upgraded design that, according to AnanTech, will reduce power consumption by 40-50% and "dramatically reduced standby power by 3 orders of magnitude.
Broadcom itself describes the dual-band chip as follows:
The Broadcom BCM4334 single-chip dual-band combo chip provides a complete wireless connectivity system with ultra-low power consumption for mass market smartphone devices. Using advanced design techniques and 40nm process technology to reduce active and idle power, the BCM4334 is designed to address the needs of highly mobile devices that require minimal power consumption and compact size while delivering dual-band Wi-Fi connectivity.
... The combo device also features advanced switching techniques that enable concurrent dual-band operation to simultaneously support network connectivity with one band while also allowing content streaming via technologies such as Wi-Fi Display and Wi-Fi Direct.
The advanced architecture supports the latest "always on always connected" (AOAC) applications such as push e-mail or Internet radio services, even while the host smartphone is in sleep modes, further preserving battery life...
Solid stuff, and assuming the next-gen iPhone will in fact support 4G LTE and house a larger display, conserving power at every opportunity will have to be a priority for Apple.
Lastly, pervious reports have indicated that the processor that will power the iPhone 5 may not be an A6, but rather a modified and enhanced version of the A5, much like the one that currently powers the latest iPad. Also, the next-gen iPhone will reportedly sport 1GB of RAM.
